In 1854, in Ajo, Arizona, the Arizona Mining and Trading Company launched the modern era of hard-rock mining. A burgeoning mining industry stimulated early growth in the Arizona Territory, and by 1864 nearly 25 percent of the male, non-native populace was prospectors.

Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell. Some typical materials used for alumina in the cement manufacturing are shale, clay, slags, fly ash, bauxite, alumina process waste, and granite.

Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production. Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan and China.

Waste rock will be disposed of in four distinct waste dumps with three located around the pit and one further to the south. The open pit generates 548.9 Mt of overburden and waste rock (inclusive of historic tailings and underground backfill) over the life of mine ("LOM") for an average LOM strip ratio of 3.87:1.
